If it is a credit card of China Merchants Bank, ordinary credit card consumption has an interest-free period. 1. Interest-free period refers to the period from the bank bookkeeping date to the due repayment date (interest-free repayment period ranges from 20 to 50 days) when the cardholder repays all the payable funds before the due repayment date (inclusive). 2. If you repay the full amount on time before the final repayment date, you can enjoy the interest-free period of credit card consumption without charging any fees. 3. The minimum repayment amount refers to the minimum monthly repayment amount, which is shown on the bill of the current month without application. Paying off the minimum repayment amount on time will not affect personal credit, but you cannot enjoy the interest-free period. All consumption in the current period will bear interest from the bookkeeping date, with a daily interest rate of five ten thousandths.
